I have exactly the same problem with you dude, my friends too. When i open flv/html5 video from youtube, dailymotion or any other video streaming site with waterfox, the video somewhat played with some lag even when it's finished buffering (so it's not internet connection problem). But when i use firefox (32-bit) or chrome (32-bit) it plays smoothly, i tried to unistall firefox and waterfox and re-install waterfox again, but it still the same laggy video. I don't know, maybe the problem is either in waterfox or the flash-player (64-bit).

I been having problems with YT loading anything for the longest time. It might be WF or 64bit FP I'm not sure. But I do have Safari onboard so I can check with that to see if it's related to my 64bit browser....

Yeah nope, still have the same issue in my 32bit browser that I have with watching with my 64bit. Imho, it's YouTube. Quality feeds are gone and now you're lucky to get a vid to upload on the first take without refreshing it at least 3 times in order to get the whole thing to buffer. FailTube is pissin me off to no end. It's not my system, it's not my connection speed. It's FailTube.

HI

i am glade i saw this posts and now i can comment , as far it concern me , i also got long time issue with YT playing clips , its run very jitter especially when moving the mouse pointer around the screen fast (in any direction).

this problem exist in ALL firefox based engine (ff11 x32 , palemoon x32+x64 , waterfox x32+x64) , the only browser that this issue gone is CHROME + OPERA .

i of course disable "hardware acceleration " which reduce the "bad running " a little bit ....i think its related to flash player combine with firefox .

Well I'm glad to see there's others having the same issue with all Firebox based browsers. I did some checking and saw that Mozilla has been making changes with the way media is handled and updating their media controls. Here's what I found:

Feature overview

Our HTML5 media controls have changed very little since they were introduced in Firefox 3.5 -- mostly just bug fixed and keeping them working as the spec evolves. HTML5 media is an area we've made serious investment in, and it's time to make sure our default controls show it.

This project is primarily a collection of bug-fixes, updated design work, and small-scope featurettes; all building on top of the existing implementation.

(fixed, FF9) bug 462117 – Add specialized video controls for small-dimension media.
(fixed, FF10) bug 513758 - Pressing Pos1/End key while video is in ended state sets status to play
(fixed, FF11) bug 699719 - Fade out video controls if no mouse movement for > n seconds
So as you can see, work is being done to improve media controls and the way media plays. Some other changes is Mozilla will change to VC2010 to build Firefox after Firefox 13 and they are changing out their code to an improved better code. So lots of changes are being made which will improve Firefox in all areas. By the way, YouTube has recently changed from Flash based videos to HTML 5. This could be what's causing the problems. Take a look at the following link for more info:

I think the problem is YouTube. Google owns both Chrome and YouTube so that's why the video plays perfectly on their browsers. They decided to change from Flash to HTML 5 suddenly and in the process, lots of other browsers are having these issues. Thanks again Google for making your browser look good and screwing everyone else! Anyway, give it a little time and other browsers will completely switch to what Google wants and all video will play smooth again.Edited by djkilla - 4/23/12 at 7:24am

Well, a challenge! I read the article and laughed at the results. Why you ask? There are different scenarios as to how Firefox 32bit and Waterfox 64bit will run on a machine. Hardware being one, settings being another, the amount of addons and extensions, etc.. Lets take a look at his scores using Peacekeeper. My score is 2078. I clearly have a very fast Waterfox browser but how? Well, let's take a look at what I've got. I'm using Waterfox on a SSD drive. I'm also using the speed tweaks in my post #2057. I also only have one plugin, Adobe Flash. I only have ten addons/extensions. Here they are:

There's more to consider but with what I've got and how it's setup, I'm getting great scores. Using Dromaeo to speed test, I even did better than all the browsers tested by a member who uses Pale Moon 64bit. I scored 472.77. Here are their results:

Take a look at the Total Score at top of each browser. Like I said, my score is 472.77. So a lot of factors are involved when it comes to how well Waterfox 64bit performs. My suggestion, if you're comparing browsers, don't have any addons/extensions or plugins in both browsers. Then run the tests yourself. You can use the speed tests located in my post #2074 and see my results at the bottom of that post.

Which means what we are experiencing is probably normal? The thing is that for me I don't experience the same problem with FF11 (32-bit)? It's working flawlessly with that browser.
